JOHN R. DGOTY, OF LIBERAL, KANSAS, ASSIGNOR TO CLARENCE IE. WILLIAMS,OF` i MIAMI, OKLAHOMA LATCH LUBRICATOR Application med my e, 1931rserial N. 548,986.-

My invention relates to lubricators forV latch-bolts on swingingclosures, and is more particularly designed for use upon automobiledoors.

The objects of my invention are to provide a device of this class whichis new, novel, practical and of utility; which may be easily and quicklyinstalled adjacent and beneath the usual keeper of a door latch bymerely loosening the usual screws or bolts which hold the keeper inplace; which is constructed of a single sheet of bendable metal and asingle fibrous pad, the pad being retained in position on the sheet byan integral convolute gf portion or portions thereof, thus permittingthe entire sheet to be formed and t-he pad installed by a singleoperation of a stamping machine; which has no moving parts to becomeworn or to get out of order; which will thoroughly lubricate thebevelled end of a latch-bolt; which will act as a silencer to preventsqueaks and rattles, as well as acting as a shock absorber for thelatch-bolt when a door is closed; which will be durable; which iscomparatively cheap to manufacture; and, which will be efficient inaccomplishing all of the purposes for which it is intended.

There have been in the past some devices perfected for lubricating thebevelled free :e end of a latch-bolt, but so far as this applicant knowsor has been able to ascertain these devices are all constructed so thatthey move with the latch-bolt as its free end enters the latch-plate orkeeper. This necessarily causes 35 them to wear more severely than woulda stationary pad. They are also more complicated to manufacture andinsta-1l than is applicants device.

Applicant is also familiar with a number of devices designed to silencethe contact of a latch-bolt with its keeper, but so far as he knows orhas been able to ascertain these devices are all considerably morecomplicated to install and manufacture and are much more expensive thanhis device.

With these and other objects in view as will more fully appear, myinvention consists in the construction, novel features, and combinationof parts hereinafter more fully 50 described, pointed out in the claimshereto appended,'andillustrated in the accompanying one-sheet drawing,of which,

Figure l is a fragmentary view of a door ]amb showing a usual type oflatch-plate or keeper'in place, and showing the device installed foruse;

ig. 2 is a perspective view of the device; an Y c v Fig. 3 is a viewsimilar to that of Fig. 2, showingfthe bevelled end of a usual latchboltseated upon the lubricating portion of the device.

Like characters of reference designate like parts in all of the figures,

It is understood that various changes in the form, proportion, size,shape, weight, and other details of construction, within the scope of myinvention may be resorted to without departing from thel spirit or.broad principle of my inventionand without sacriicing any of theadvantages thereof; and it is also to be understood that the drawing isto be interpreted as being illustrative and not restrictive. v Y

One practical embodiment of the invention as illustrated in the drawingfollows:

The device as a whole is indicated by the reference numeral l, andconsists substantially of a sheet of metal which at one yend isbifurcated to form parallel flat legs 2. The other end portion of thedevice is arcuately formed to seat within the usual cavity in a jambmember 9 for seating the free bevelled end of a usual latch-bolt 3. Thisarcuate portion is indicated by the reference numeral 10 and its innersurface is covered by a fibrous pad 11 held in place by a convoluteportion l2 of the sheet forming the device. Said pad 1l is adapted to besaturated with a desired lubricant.

In Fig. 1, the reference numeral l indicates a usual keeper which isheld in position upon the jamb member 9 by a plurality of bolts orscrews 5 and 6. Said keeper t is so positioned that one end coincideswith one side of the previously mentioned cavity within which thearcuate portion 10 of the device is positioned. y

In installing the device upon the jamb member 9, all that is necessaryis to loosen the screws 5 and 6 a short distance; insert the legs 2between the keeper 4 and the face of the j amb member 9, the legsassuming a position upon each side of the screws 5 and 6; and, to thenre-ti hten the screws.

It maybe seenl rom the foregoing descrip'- tion that applicant hasprovided lan extremely simple device which will accomplish all of thepurposes for which it is intended.

Obviously, the invention is susceptible of embodiment in forms otherthan that which is illustrated in the accompanying drawing and describedherein, and applicable for uses and purposes other than as detailed, andI therefore consider as my own all such modifications and'adaptationsand other uses of the form of the device herein described as fairly fallwithin the 'scope of my invention.

vHaving thus described lmy invention, what is claimed and desired to besecured by Letters Patent is:

1L An oiling device for the lfree end of a latch-bolt, consisting of asingle plate of thin metal having a pad of `fibrousV material forreceiving oil, said pad caught in a convolute portion of saidk plate adjacent-one end thereof, said plate having two integral legs for insertionbetween a keeper and its supporting member for rigidly `positioning thepad at one end of the keeper for seating the free end of a latch-bolt. Yl f 2. An oiling device for the free end of la latch-bolt, consisting ofa single plate of thin metal having a pad of fibrous material forreceiving alubricant, said pad caught in a convolute portion of saidplate adjacent one end thereof, `said plate having two parallel integrallegs for insertionr between a keeper and its supporting member so asto'straddle the usual keeper positioning screws for rigidly positioningthe pad 'at one end of the keeper for seating the free end `of thelatch-bolt when the keeper positioning screws are tightened. s

In testimony whereof I affix my signature.
